[Nickle] nickle from CVS (2002-12-04) fails loading builtins

[Carl Worth]

I recently found nickle crashing on a trivial and innocent-looking
file:

	$ cat foo.5c 
	public typedef struct {
	  int x;
	} foo;
	
	foo bar;
	
	$ /usr/local/bin/nickle foo.5c 
	Segmentation fault

I checked and I had last updated nickle on 2002-09-12, (I also had an
older version from 2002-08-12 that didn't have the problem).

I tried updating to current CVS, but now nickle fails to start:

	$ nickle
	->     if (!lex_library (name))
	/usr/local/share/nickle/builtin.5c:21: No visible symbol "lex_library"
	in scope
	/usr/local/share/nickle/builtin.5c:31: parse error before
	"\"string.5c"
	/usr/local/share/nickle/builtin.5c:32: parse error before "\"ctype.5c"
	/usr/local/share/nickle/builtin.5c:33: parse error before
	"\"printf.5c"

	/usr/local/share/nickle/builtin.5c:51: parse error before "ARC4"
	/usr/local/share/nickle/builtin.5c:52: parse error before "PRNG"
	->     Command::script_dir (Command::dirname (argv[0]));
	/usr/local/share/nickle/builtin.5c:60: No visible symbol "script_dir"
	in scope
	->     Command::script_dir (Command::dirname (argv[0]));
	/usr/local/share/nickle/builtin.5c:60: No visible symbol "dirname" in
	scope

Are others seeing this or is it just me?

I don't know if the bug causing the segfault is resolved yet or not.

PS. I only wrote 20 lines of nickle code yesterday, and I've already
run into two problems... I guess that means I get to write my next 80
lines of code without hitting any nickle bugs, right Bart?
